This patent application is a continuation of U.S. application Ser. No. 13/051,837, filed Mar. 18, 2011, which claims priority to U.S. Provisional Application No. 61/323,655 filed Apr. 13, 2010, entitled “Camera As A Vehicle To Identify Location,” both of which are hereby incorporated by reference in their entirety for all purposes.

BACKGROUND

Identity theft and identity fraud have become increasingly serious problems as devices for engaging in financial transactions have increased in number. These fraudulent activities have become very costly to consumers, merchants, financial institutions, and others.

Prior systems provide various fraud deterrent techniques. For example, near field communications protocols, such as Bluetooth and RFID, allow a consumer to exchange transaction information with a merchant without physical contact between the consumer's near field communication enabled payment device and the merchant's near field communication enabled access device. The problem is that all consumers do not have payment devices that support near field communications. Thus, all consumers cannot take advantage of contactless payment mechanisms.

Embodiments of this disclosure address these and other problems, individually and collectively.

BRIEF SUMMARY

Embodiments of the present invention relate in general to financial transactions and in particular to systems and methods for using a camera as a vehicle to identify the location of a merchant access device of a merchant.

According to one embodiment, a method includes acquiring, during a transaction between a consumer and a merchant via a merchant access device associated with the merchant, an image of the merchant access device, the image including characteristics of the merchant access device, and communicating the image to a server computer. The server computer subsequently identifies the merchant access device from a plurality of merchant access devices using the characteristics of the merchant access device included in the communicated image.

According to another embodiment, a method includes receiving, during a transaction between a consumer and a merchant via a merchant access device associated with the merchant, an image of the merchant access device, the image including characteristics of the merchant access device, and identifying the merchant access device from a plurality of merchant access devices using the characteristics of the merchant access device included in the received image, and sending an authorization response message to the merchant access device.

DETAILED DESCRIPTION

Embodiments of the invention disclosed herein include systems and methods for using a camera as a vehicle to identify a merchant access device of a merchant.

A consumer may use a mobile communication device such as a cell phone to engage in a transaction with a merchant. The merchant may have a merchant access device such as a Point of Sale terminal to display transaction information and, in some cases, receive account information from the consumer. The mobile communication device in embodiments of the present invention includes a camera to process transactions with the merchant. The camera enables the consumer to engage in the transaction with the merchant without providing account information to the merchant.

Instead of providing account information to the merchant, the consumer may use the camera to acquire an image of the merchant access device. Merchant access devices typically have unique characteristics by which they can be identified. Accordingly, the image will capture such characteristics. The consumer may then send the image to a server in a payment processing network such as VisaNet via the mobile communication device. The server may then compare the image to images stored in a database in order to identify the merchant access device used. In some embodiments, the comparison may be performed by the mobile communication device. The consumer, at the same time, may also provide account information to the server via the mobile communication device. Further, the server may obtain transaction information, such as the amount of the transaction which needs to be authorized. The server may obtain the transaction information from either the consumer via the mobile communication device or from the merchant.

Once the server has acquired all of this information, the server may then use such information to determine whether the transaction is authorized, or send the information to an issuer for authorization. An authorization response message may then be returned to the consumer and merchant via mobile communication device and/or merchant access device. While the account information is used to identify an account associated with the consumer, the transaction information is used to identify the amount of the transaction which needs to be authorized, and the image is used to identify the merchant access device so that the authorization response message may be communicated to the appropriate merchant and merchant access device.

Certain embodiments of the invention may provide one or more advantages to consumers, merchants, issuers, and others. An advantage to a consumer is that his identification information is more secure. Since the consumer can communicate the transaction and identification information directly to the payment processing network through his mobile communication device, the merchant access device (e.g., point of sale terminal) no longer requires the identification information to conduct the transaction. Thus, the consumer does not need to provide his identification information to the merchant access device, which eliminates the problem of identity theft at the merchant access device. In many cases, identity theft can occur when the merchant access device is located at a fraudulent merchant or when the merchant access device itself is unauthorized, because it was placed at a legitimate merchant by an unauthorized person. Further, a direct line of communication from the consumer to the payment processing network is easier to protect and thus more secure. For example, the mobile communication device can include a secure chip with encryption software. Since the server computer of the payment processing network communicates directly with the mobile communication device, the server computer of the payment processing network can provide frequent and timely updates of encryption software to the mobile communication device. Thus, the consumer's identity information is more secure in this system.

Another advantage to a consumer is that the consumer has more control over his identity information and over the transaction in general. In prior systems, the consumer had to provide his identity information (e.g., a PAN or personal account number) to the merchant access device (e.g., the point of sale terminal) in order to conduct a transaction. In this system, the mobile communication device has much of the functionality of a merchant access device. The mobile communication device can be used to initiate, authorize, and/or terminate the transaction. Since the consumer is in control of the mobile communication device, the consumer decides when to conduct the transaction and to whom he will provide his identity information. Thus, control of the transaction and identity information is given back to the consumer.

An advantage to merchants and issuers is that these methods and systems are easier to secure and can prevent monetary losses due to identity theft. As discussed above, these systems are inherently more secure and thus should reduce fraud and money lost to fraud. Further, the issuer can save money by concentrating their fraud deterrent efforts on protecting information communicated between the server computer of the payment processing network and the mobile communication device.

An advantage to the payment processing network is that the network can more easily secure the communications to the consumer. As discussed above, the mobile communication device can include a secure chip with encryption software which is frequently updated by the payment processing network. Also, the encryption algorithms can be more complex since communications are not sent through a series of other entities.

Another advantage to the payment processing network is that the payment processing network can develop a more sophisticated transaction process since it has a more detailed account of the transaction. The mobile communication device can receive greater detail about the transaction and relay it to the payment processing network. With increased information, the payment processing network has the opportunity to develop new and more sophisticated techniques of processing transactions.

Certain embodiments of the invention may include none, some, or all of the above technical advantages. One or more other technical advantages may be readily apparent to one skilled in the art from the figures, descriptions, and claims included herein.

Before discussing specific embodiments of the invention, some descriptions of some specific terms are provided below.

Transaction information: may be any suitable information related to the transaction. For example, at least one of a list of the items in the transaction, a description of the items, item identifiers (e.g., stock keeping units or SKUs), prices of the items being purchased, the total number of items, the total amount of the transaction, and a transaction code. A transaction code is associated with a specific transaction and can be used to identify other transaction information.

Characteristics of the merchant access device: may be unique feature(s) of the merchant access device which may be used to identify the merchant access device. For example, a shape of the merchant access device, a color or arrangement of colors on the merchant access device, an arrangement of elements provided on the merchant access device, where the elements includes at least one of a keypad, a display, a magnetic strip card reader, a printer, a smart card reader, an antenna, and information indicating a unique identifier associated with the merchant access device located outside a display of the merchant access device.

Location data: may be information sufficient to identify a particular location. For example, global positioning system (GPS) coordinates, geographical coordinates (i.e., latitude and longitude), Universal Transverse Mercator (UTM) coordinates, Universal Polar Stereographic (UPS) coordinates, Cartesian coordinates, and a mailing address.

Account information: may be information sufficient to identify a particular account issued by an issuer. For example, a phone number, an alphanumeric sequence (e.g., a name of the consumer, a name of the account, etc.), a dialing tone or sequence of dialing tones, an image or sequence of images (e.g., a picture of the consumer, a fingerprint, etc.), and an audio sequence.

Authorization request message: may be a message that includes a consumer account identifier. The consumer account identifier may be a payment card account identifier associated with a payment card. The authorization request message may request that an issuer of the payment card authorize a transaction. An authorization request message according to an embodiment of the invention may comply with ISO 8583, which is a standard for systems that exchange electronic transactions made by cardholders using payment cards. An authorization request message may comprise data elements including, in addition to the account identifier, a service code, a card verification value (CVV), and an expiration date.

Authorization response message: may be an issuing financial institution's electronic message reply to an authorization request, which may include one or more of the following status indicators: Approval—transaction was approved; Decline—transaction was not approved; or Call Center—response pending more information, merchant must call a toll-free authorization phone number. It may also include an authorization code, which may be a code that a credit card issuing bank returns in an electronic message to the merchant's point of sale (POS) terminal that indicates approval of the transaction. The code serves as proof of authorization.

Merchant access device identifier: may be an identifier which identifies a particular merchant access device. For example, an alphanumeric sequence (e.g., a serial number, IP address, MAC address, etc.), a purely alphabetical sequence, a purely numeric sequence, and the like.

Consumer account identifier: may be an identifier which identifies a particular consumer account. For example, an alphanumeric sequence (e.g., an account number issued by an issuer, a number of a payment card issued by an issuer, etc.), a purely alphabetical sequence, a purely numeric sequence, and the like.

I. Exemplary System with Mobile Phone Having Camera

FIG. 1 is a block diagram of an exemplary system 100 for conducting a payment transaction using a camera in a mobile communication device 120 as a vehicle to identify a merchant access device 132, according to one embodiment of the invention. System 100 includes consumer 110, mobile communication device 120, merchant 130, acquirer 140, payment processing network 150, and issuer 160.

Consumer 110 may use mobile communication device 120 in a purchase transaction. Merchant 130 may have merchant access device 132 used to process transactions with consumer 110. Consumer 110 may interact with merchant 130 using mobile communication device 120. Mobile communication device 120 includes a camera and is capable of communicating with payment processing network 150 and, in some embodiments, issuer 160. Merchant 130 is in communication with acquirer 140. Acquirer 140 is in communication with issuer 160 through payment processing network 150. Payment processing network 150 is also in communication with merchant 130.

Consumer 110 may be an individual or an organization such as a business that is capable of using mobile communication device 120 to conduct a transaction such as a purchase of goods and/or services. Consumer 110 has an account with issuer 160 that may be associated with mobile communication device 120.

Mobile communication device 120 refers to any suitable wireless device that allows consumer 110 to conduct transactions with merchant 130 and communicate information with other entities such as payment processing network 150 or issuer 160. Some examples of suitable devices include cellular or wireless phones, personal digital assistants (PDAs), pagers, portable computers, and the like. Suitable mobile communication devices can be hand-held and compact so that they can fit into a consumer's wallet and/or pocket (e.g., pocket-sized). Such mobile communication devices may include a cellular antenna, a GPS antenna, a computer readable medium (CRM) embodied by one or more memory devices, input elements (e.g., a keypad), output devices (e.g., a screen), a microphone, a speaker, and a contactless element, all operatively coupled to a processor. Mobile communication device 120, regardless of its form, includes a camera (not illustrated) operatively coupled to the processor. The camera is operable to acquire images as is known in the art.

Mobile communication device 120 is operable to communicate information to other system entities in any suitable form. Some examples of suitable forms include a short message service (SMS) message such as a text message, a multimedia media message (MMS), a phone call, a voice message, a voicemail message, an instant messaging (IM) message, an email message, etc. Mobile communication device 120 is also operable to communicate images acquired via the camera in any suitable form. Some examples of suitable forms include MMS, IM with imaging capability, an email message, etc. In some cases, the system entity receiving the message (e.g., server computer 152 of payment processing network 150) may require a PIN before authorizing the transmission for security purposes. Consumer 110 enters the PIN into mobile communicating device 120 or other device communicating with the entity. The PIN is then sent to the entity. Once the entity verifies the PIN, the requesting entity will authorize the transmission of the message. For example, to send an SMS message to server computer 152 of payment processing network 150, server computer 152 of payment processing network 150 may request a PIN, receive the PIN, and verify that the PIN is valid before allowing transmission of the SMS message.

In embodiments of the invention, issuer 160 may be associated with mobile communication device 120 in any suitable manner. For example, issuer 160 may have an account that is linked to the phone number in mobile communication device 120. In another example, issuer 160 may have a virtual payment card that is stored on mobile communication device 120.

Merchant 130 can be any suitable entity or entities that make a payment transaction with consumer 110. Merchant 130 may use any suitable method to make the payment transaction. For example, merchant 130 may be a department store, a gas station, a drug store, a grocery store, or other suitable business.

Merchant access device 132 refers to any suitable device for processing transactions with merchant 130 and for interacting with mobile communication device 120. Suitable access devices may include Point of Sale (POS) devices, cellular phones, PDAs, personal computers (PCs), tablet PCs, handheld specialized readers, set-top boxes, electronic cash registers (ECRs), automated teller machines (ATMs), virtual cash registers (VCRs), kiosks, security systems, access systems, and the like. According to some embodiments, merchant 130 has a plurality of merchant access devices. Each merchant access device may then be associated with a unique identifier that distinguishes it from other merchant access devices that merchant 130 has. Each merchant access device may also have a unique identifier that distinguishes it from merchant devices of other merchants. According to other embodiments, merchant 130 only has a single merchant access device.

Merchant access device 132 may use any suitable contact or contactless mode of operation to communicate data to and from mobile communication device 120. For example, merchant access device 132 can use a wireless communication mode including near field communication such as Bluetooth, infrared, etc. However, benefits from embodiments of the present invention are particularly realized when such wireless communication modes are not available.

Acquirer 140 can be any suitable entity that has an account for merchant 130 and that processes merchant transactions associated with merchant access device 132. For example, acquirer 140 may be a bank that operates a bank account for merchant 130.

Merchant access device 132 may be associated with any or all of this type of information.

FIG. 2B is a diagrammatic representation of consumer database 158 storing phone numbers of mobile communication devices and their association with consumer account identifiers, according to one embodiment of the invention. That is, an account for consumer 110 issued by issuer 160 may be associated with a phone number. Consumer database 158 may store a consumer account identifier. The consumer account identifier may be an identifier which identifies a particular consumer account. For example, an alphanumeric sequence (e.g., an account number issued by an issuer, a number of a payment card issued by an issuer, etc.), a purely alphabetical sequence, a purely numeric sequence, and the like. Consumer database 158 may also store the phone number, and an association between the consumer account identifier and the phone number.

According to some embodiments, consumer database 158 may additionally or alternatively store other account-related information linked to the consumer account identifier. For example, consumer database 158 may store an alphanumeric sequence (e.g., a name of the consumer, a name of the account, etc.), a dialing tone or sequence of dialing tones, an image or sequence of images (e.g., a picture of the consumer, a fingerprint, etc.), an audio sequence, etc. The consumer account identifier may be associated with any or all of this type of information.

Returning to FIG. 1, issuer 160 may be any suitable entity that can approve a transaction, and may optionally open and maintain an account associated with consumer 110. For example, issuer 160 may be a bank, a business entity such as a retail store, or a governmental entity that issues a payment account to consumer 110. In many cases, issuer 160 may also issue a payment card to consumer 110. In some embodiments, issuer 160 may also be the acquirer 140.

Issuer 160 includes a server computer 162. Server computer 162 refers to a powerful computer or cluster of computers. For example, server computer 162 can be a large mainframe, a minicomputer cluster, or a group of servers functioning as a unit. In one example, server computer 162 may be a database server coupled to a Web server (not shown). Server computer 162 includes a processor 164 coupled to a CRM 166. CRM 166 comprises code for performing the functions of server computer 162, where processor 164 functions to execute the code.

Issuer 160 may also include a database (not shown) coupled to server computer 162. The database refers to any hardware, software, firmware, or combination of the preceding for storing and facilitating retrieval of information. The database may use any of a variety of data structures, arrangements, and compilations to store and facilitate retrieval of information. The database may store any suitable data. Issuer 160 may use any suitable wired or wireless network, including the Internet, to communicate with other entities.

In a typical payment transaction between consumer 110 and merchant 130, consumer 110 purchases goods or services at the merchant 130. During the transaction, merchant access device 132 may show the total purchase amount and/or may show a listing of the purchased items. At this point, consumer 110 may use a camera in mobile communication device 120 to take a picture of merchant access device 132. Consumer 110 may then communicate the picture to server computer 152 of payment processing network 150 or server computer 162 of issuer 160. Most merchant access devices are unique in appearance or have unique characteristics, which can make them identifiable. This information can be used by a remoter server computer to determine the exact access device that was used to conduct the transaction. In some embodiments, consumer 110 may also use mobile communication device 120 to send location data to server computer 152 of payment processing network 150. The location data may indicate a location of mobile communication device 120. The location data may be used along with the picture to determine the exact merchant access device that was used to conduct the transaction.

Merchant access devices may have various characteristics which make them unique. For example, unique characteristics for purposes of identification may include at least one of a shape of the merchant access device, a color or arrangement of colors on the merchant access device, and an arrangement of elements provided on the merchant access device. The elements may be any of those typically found on merchant access devices. For example, they may include at least one of a keypad, a display, a magnetic strip card reader, a printer, a smart card reader, and an antenna. Other unique characteristics may include a unique identifier associated with the merchant access device. For example, the unique identifier may be an alphanumeric number or element associated with the merchant access device, a serial number associated with the merchant access device, or a barcode associated with the merchant access device. In some embodiments, the unique identifier is provided on a display of the merchant access device. In other embodiments, the unique identifier is provided on portions of the merchant access device other than the display.

According to some embodiments, identification of a merchant may be sufficient to identify a particular merchant access device. For example, where a merchant only has a single merchant access device, identification of the merchant is sufficient to identify the merchant access device. In such cases, merchant access devices may need only provide characteristics sufficient to identify the merchant. For example, unique characteristics may include at least one of a trademark associated with the merchant, a structural element of a merchant access device provided only to a particular merchant; a graphical element of a merchant access device provided only to a particular merchant, an alphanumeric number or element associated only with the merchant, and a serial number associated only with the merchant.

According to other embodiments, information indicating unique characteristics of a merchant and/or merchant access device may be combined with location data to identify at least one of a merchant access device and a merchant. Various types of location data have previously been discussed.

In one embodiment, location data may be generated by mobile communication device 120. For example, mobile communication device 120 may use a GPS antenna to determine the GPS coordinates of mobile communication device. In another embodiment, location data may not be generated by mobile communication device 120, but instead, may be provided from another source. For example, if mobile communication device 120 is a mobile telephone, server computer 152 may contact the carrier hosting mobile communication device 120 in order to receive the location data of mobile communication device 120. The location data may be generated using, for example, triangulation methods. In yet another embodiment, location data may be communicated to server computer 152 of payment processing network 150 by consumer 110. For example, consumer 110 my input location data into mobile communication device 120 which subsequently relays such information to server computer 152 of payment processing network 150.

In one embodiment, the image acquired by mobile communication device 120 may include the unique characteristics associated with merchant access device 132 along with transaction information. The transaction information may include, for example, at least one of a list of the items in the transaction, a description of the items, item identifiers (e.g., stock keeping units or SKUs), prices of the items being purchased, the total number of items, the total amount of the transaction, and a transaction code. A transaction code is associated with a specific transaction and can be used to identify other transaction information. The transaction information may then be sent to server computer 152 of payment processing network 150 by mobile communication device 120.

In another embodiment, consumer 110 may input transaction information into mobile communication device 120. The transaction information may then be sent to server computer 152 of payment processing network 150 by mobile communication device 120.

In other embodiments, the transaction information may be sent to server computer 152 of payment processing network 150 by merchant 130 or merchant access device 132 instead of mobile communication device 120. For example, the transaction information may be sent directly to server computer 152 of payment processing network 150 from merchant access device 132. For another example, the transaction information may be sent to server computer 142 of acquirer 140 from merchant access device 132, and then server computer 142 of acquirer 140 may then subsequently send the transaction information to server computer 152 of payment processing network 150. For yet another example, after identifying merchant access device 132, server computer 152 of payment processing network 150 may directly communicate with merchant access device 132 in order to obtain the transaction information.

Using mobile communication device 120, consumer 110 sends account information to server computer 152 of payment processing network 150. The account information identifies an account associated with consumer 110 and issued by issuer 160. In one embodiment, consumer 110 may send the account information directly to server computer 152 of payment processing network 150. For example, consumer 110 may enter, into mobile communication device 120, an account number or other information recognized by issuer 160 to identify the account issued to consumer 110. Consumer 110 may then cause mobile communication device 120 to send such information to server computer 152 of payment processing network 150. In other embodiments, server computer 152 of payment processing network 150 may deduce the account associated with consumer using information sent by mobile communication device 120. For example, mobile communication device 120 may send a phone number of mobile communication device 120 to server computer 152 of payment processing network 150. Server computer 152 of payment processing network 150 may then compare the received phone number with phone numbers stored in consumer database 158 to determine a matching phone number. Server computer 152 may then identify a consumer account identifier associated with the matching phone number. As previously described, the consumer account identifier identifies the account for consumer 110 issued by issuer 160. In other embodiments, server computer 152 of payment processing network 150 may receive the phone number of mobile communication device 120 from another entity, such as a telecommunications company or network associated with mobile communication device 120.

Using the data retrieved from the image and, in some embodiments, the location data, server computer 152 of payment processing network 150 identifies the particular merchant access device associated with merchant 130 that is used to perform the payment transaction between merchant 130 and consumer 110. Prior to the transaction, images, geographical locations, or other information about the various merchant access devices used at various merchants may be stored in merchant database 156 and may be mapped to merchant access device identifiers. Examples of such information have previously been described, and such descriptions are equally applicable herein. Also, a table mapping account information such as phone numbers to consumer account identifiers may be present in consumer database 158. Examples of such information have also previously been described, and such descriptions are equally applicable herein. Using information such as this, server computer 152 of payment processing network 150 then generates and sends an authorization request to issuer 160. For example, server computer 152 may identify the merchant, the specific merchant access device being used, and the amount of the transaction, from the information that has been received and from the information in the database. It may also identify the consumer account number (as well as expiration date and other payment card information) from the consumer's phone number. All or some of this information may be included in the authorization request message that is sent to server computer 162 of issuer 160.

Upon receiving the authorization request, issuer 160 processes the authorization request message and determines whether to authorize or decline the transaction. Once issuer 160 decides whether to authorize or decline the transaction, server computer 162 of issuer 160 generates and sends an authorization response message which indicates whether the transaction is approved or declined. Issuer 160 may decline the transaction for a variety of reasons (e.g., insufficient funds, risky transaction, etc.).

According to one embodiment, issuer 160 sends the authorization response message to server computer 152 of payment processing network 150. Server computer 152 then sends the authorization response message to server computer 142 of acquirer 140. Server computer 142 of acquirer 140 then forwards the authorization response message to merchant 130 or merchant access device 132. Merchant 130 or merchant access device 132 may provide the authorization response message to consumer 110. For example, the data associated with the authorization response message may be displayed on a display of merchant access device 132 or may be printed on a receipt. In some cases, server computer 152 of payment processing network 150 sends the authorization response message directly to consumer 110. For example, the authorization response message may be sent from server computer 152 of payment processing network 150 directly to mobile communication device 120 without being sent through acquirer 140 or merchant 130. The data associated with the authorization message may then be displayed on a display of mobile communication device 120.

In some cases, payment processing network 150 can authorize the transaction on behalf of issuer 160. In these cases, payment processing network 150 processes the information received from mobile communication device 120. After processing, server computer 152 of payment processing network 150 has information about the consumer using mobile communication device 120, the issuer having an account associated with mobile communication device 120, the merchant and/or merchant access device engaged in the transaction, and the transaction. With this information, server computer 152 of payment processing network 150 can determine whether to authorize or decline the transaction on behalf of issuer 160. Server computer 152 sends an authorization response message to acquirer 140. Server computer 142 of acquirer 140 forwards the authorization response message to merchant 130 which forwards it to consumer 110. Server computer 152 may also send a message to issuer 160 indicating that the transaction has been authorized on their behalf and including other suitable information required by issuer 160 to process the transaction.

In one embodiment, mobile communication device 120 relays some or all information directly to issuer 160. The information may be sent in any suitable form such as an authorization request message. In this embodiment, issuer 160 determines whether to authorize or decline the transaction based on the information received from mobile communication device 120. If issuer 160 requires more information from consumer 110 to decide whether to authorize or decline the transaction, server computer 162 of issuer 160 may send a request message for more information to consumer 110 through mobile communication device 120 (or, in some embodiments, through merchant 130 or merchant access device 132). Once issuer 160 decides whether to authorize or decline the transaction, server computer 162 of issuer 160 directly or indirectly sends an authorization response message to at least one of mobile communication device 120, merchant access device 132, and merchant 130.

In another embodiment, server computer 152 of payment processing network 150 may send the authorization response message directly to mobile communication device 120 operated by consumer 110 instead of to merchant access device 132. Consumer 110 can provide the authorization response message to merchant 130 using mobile communication device 120. For example, consumer 110 may cause mobile communication device 120 to pass by a contactless reader of merchant access device 132 so that the merchant access device 132 can read the authorization response message from mobile communication device 120.

In some embodiments, at least one of merchant database 156 and consumer database 158 are provided in mobile communication device 120. In such cases, mobile communication device 120 may be operable to perform the comparisons and identifications using merchant database 156 and consumer database 158 previously described with respect to server computer 152 of payment processing network 150. In such cases, after performing such comparisons and identifications, mobile communication device 120 may communicate the results of such comparisons and identifications to sever computer 152 of payment processing network 150 or server computer 162 of issuer 160.

At the end of the day, a normal clearing and settlement process may be conducted. A clearing process is a process of exchanging financial details between merchant 130 and issuer 160 to facilitate posting to a consumer's account and reconciliation of the consumer's settlement position. Clearing and settlement can occur simultaneously.

Modifications, additions, or omissions may be made to system 100 without departing from the scope of the disclosure. The components of system 100 may be integrated or separated according to particular needs. For example, although separate functional blocks are shown for an issuer, payment processing network, and acquirer, some entities perform all of these functions and may be included in embodiments of invention. Moreover, the operations of system 100 may be performed by more, fewer, or other system modules. Additionally, operations of system 100 may be performed using any suitable logic comprising software, hardware, other logic, or any suitable combination of the preceding.

IV. Exemplary Methods of Processing a Payment Transaction Using a Mobile Communication Device Having a Camera

FIG. 5 is a flowchart that illustrates one embodiment of a process of using a camera in a mobile communication device as a vehicle to identify a merchant access device.

In step S510, consumer 110 and merchant 130 initiate a transaction using merchant access device 132. The transaction may be for the purchase of goods or services from merchant 130 by consumer 110. Merchant 130 may enter transaction information into merchant access device 132, and such information may be stored by merchant access device 132 and displayed to consumer 110 on a display of merchant access device 132. Various types of transaction information have previously been described, and such descriptions are equally applicable herein.

In step S520, in order to get approval to complete the transaction, consumer 110 acquires an image of merchant access device 132 using mobile communication device 120. Consumer 110 may have mobile communication device 120 in their possession during the transaction. Consumer 110 may use camera 314 of mobile communication device 120 to acquire the image of merchant access device 132.

According to some embodiments, the image includes information sufficient to identify merchant access device 132 from a plurality of merchant access devices, such as information indicating characteristics of merchant access device 132 as previously described. According to other embodiments, the image includes information sufficient to identify merchant 130 from a plurality of merchants, such as information including unique characteristics of merchants as previously described. According to yet other embodiments, the image includes transaction information as previously described. For example, the image may include some or all of transaction information displayed by a display on merchant access device 132.

In some embodiments, consumer 110 may use camera 314 of mobile communication device 120 to acquire an image of the entire merchant access device 132 or only portions of merchant access device 132. The image may include only portions of merchant access device 132 which include characteristics sufficient to identify at least one of merchant 130 and merchant access device 132. The portions may be portions of merchant access device 132 excluding output device 320 (e.g., a display) of merchant access device 132.

In step S530, consumer 110 sends the acquired image and, in some embodiments, location data via mobile communication device 120 to server computer 152 of payment processing network 150.

Location data indicates a location of mobile communication device 120 and may include any of the previously described types of location data. In one embodiment, location data comprises GPS coordinates determined by mobile communication device 120. In another embodiment, mobile communication device 120 receives input from consumer 110 indicating a location of mobile communication device 120. In yet another embodiment, mobile communication device 120 does not send location data; rather, it is sent to server computer 152 of payment processing network 150 by another source. For example, the carrier hosting mobile communication device 120 may use triangulation methods or the like to determine the location of mobile communication device 120 and the carrier may then send such information to sever computer 152 of payment processing network 150.

In step S540, server computer 152 of payment processing network 150 then uses the received image and, in some embodiments, the received location data to identify merchant access device 132.

In some embodiments, server computer 152 of payment processing network 150 uses a received image (or other information indicating characteristics of merchant access devices) to identify merchant access device 132. Prior to the transaction, images (or other information indicating characteristics of merchant access devices) are stored in merchant database 156. Examples of such information have previously been described, and such descriptions are equally applicable herein. The images are mapped to merchant access device identifiers, where each merchant access device identifier identifies a particular merchant access device. The merchant access device identifiers and the mapping between identifiers and images are also stored in merchant database 156. In response to receiving an image from mobile communication device 120, server computer 152 of payment processing network 150 compares the received image with the images stored in merchant database 156 to determine a matching image. Server computer 152 of payment processing network 150 then locates the merchant access device identifier associated with the matching image. The merchant access device identifier may then be used to identify the particular merchant access device used in the transaction.

In some embodiments, server computer 152 of payment processing network 150 uses both a received image and received location data to identify merchant access device 132. Prior to the transaction, images and location data are stored in merchant database 156. Examples of such information have previously been described, and such descriptions are equally applicable herein. Both the images and location data are mapped to merchant access device identifiers. For example, both a single image and location data indicating a particular location may be mapped to a single merchant access device identifier. The merchant access device identifiers and the mapping between identifiers, images, and location data are also stored in merchant database 156. In response to receiving an image and location data, server computer 152 of payment processing network 150 compares the received image with the images stored in merchant database 156 to determine a matching image. Server computer 152 may then compare the received location data with the location data stored in merchant database 156 to determine a matching location data. For example, if the location data is a GPS location, the received GPS location may be compared with GPS locations stored in merchant database 156 to determine a matching GPS location. Server computer 152 of payment processing network 150 then locates the merchant access device identifier associated with the matching image and the matching location data.

In some embodiments, server computer 152 of payment processing network 150 uses a received image (or other information indicating characteristics of merchant access devices) to identify merchant 130. Prior to the transaction, images (or other information indicating characteristics of merchants) are stored in merchant database 156. Examples of such information have previously been described, and such descriptions are equally applicable herein. The images are mapped to merchant identifiers, where each merchant identifier identifies a particular merchant. The merchant identifiers and the mapping between identifiers and images are also stored in merchant database 156. In response to receiving an image from mobile communication device 120, server computer 152 of payment processing network 150 compares the received image with the images stored in merchant database 156 to determine a matching image. Server computer 152 of payment processing network 150 then locates the merchant identifier associated with the matching image. The merchant identifier may then be used to identify the particular merchant used in the transaction. In some embodiments, merchant 130 is only associated with a single merchant access device. Accordingly, by identifying merchant 130, server computer 152 of payment processing network 150 effectively identifiers merchant access device 132.

In some embodiments, server computer 152 of payment processing network 150 uses both a received image and received location data to identify merchant 130. Prior to the transaction, images and location data are stored in merchant database 156. Examples of such information have previously been described, and such descriptions are equally applicable herein. Both the images and location data are mapped to merchant identifiers. For example, both a single image and location data indicating a particular location may be mapped to a single merchant identifier. The merchant identifiers and the mapping between identifiers, images, and location data are also stored in merchant database 156. In response to receiving an image and location data, server computer 152 of payment processing network 150 compares the received image with the images stored in merchant database 156 to determine a matching image. Server computer 152 may then compare the received location data with the location data stored in merchant database 156 to determine a matching location data. For example, if the location data is a GPS location, the received GPS location may be compared with GPS locations stored in merchant database 156 to determine a matching GPS location. Server computer 152 of payment processing network 150 then locates the merchant identifier associated with the matching image and the matching location data. The merchant identifier may then be used to identify the particular merchant used in the transaction. In some embodiments, merchant 130 is only associated with a single merchant access device. Accordingly, by identifying merchant 130, server computer 152 of payment processing network 150 effectively identifiers merchant access device 132.

In some embodiments, server computer 152 of payment processing network 150 uses a received location data to identify merchant 130 and a received image to identify merchant access device 132. Prior to the transaction, images and location data are stored in merchant database 156. Examples of such information have previously been described, and such descriptions are equally applicable herein. The location data may be mapped to merchant identifiers, and images may be mapped to merchant access device identifiers. According to one embodiment, each merchant is associated with a set of merchant access devices which the merchant may control. Thus, each merchant identifier may be associated with a set of merchant access device identifiers. All of this information may be stored in merchant database 156. In response to receiving an image and location data, server computer 152 of payment processing network 150 may compare the received location data with the location data stored in merchant database 156 to determine matching location data. Server computer 152 may then locate the merchant identifier mapped to the matched location data. Using the merchant identifier, server computer 152 may determine the merchant access identifiers associated with the merchant identifier. Server computer 152 may then compare the receive image with the images mapped to the associated merchant access identifiers. Server computer 152 of payment processing network 150 may then locate the merchant access device identifier mapped to the matching image. In some embodiments, the merchant identifier may be used to identify the particular merchant used in the transaction. In other embodiments, the merchant access device identifier may be used to identify the particular merchant access device used in the transaction.

Techniques for using received image and location data to identify merchant access devices and merchants are not limited to those described. Rather, other methods for using at least one of image and location data to identify at least one of merchant access devices and merchants are within the scope of the invention.

In step S550, server computer 152 of payment processing network 150 obtains the transaction information. Various types of transaction information have previously been described, and such descriptions are equally applicable herein. Further, server computer 152 of payment processing network 150 may obtain the transaction information using one or more of a variety of techniques.

In one embodiment, mobile communication device 120 communicates transaction information to server computer 152 of payment processing network 150. The information may be communicated directly to server computer 152 of payment processing network 150, or via other entities. Mobile communication device 120 may acquire the transaction information using one or more of a variety of techniques. For example, consumer 110 may input the transaction information into mobile communication device 120. For another example, mobile communication device 120 may take a picture of the transaction information. The transaction information may be in the same picture as the picture including characteristics of at least one of a merchant and merchant access device. Alternatively, the transaction information may be in a different picture. According to some embodiments, the picture including transaction information is sent to server computer 152 of payment processing network 150. According to other embodiments, mobile communication device 120 extracts the transaction information from the picture and then sends the transaction information to server computer 152 of payment processing network 150.

In another embodiment, the transaction information may be sent to server computer 152 of payment processing network 150 by merchant 130 or merchant access device 132 instead of or in addition to mobile communication device 120. For example, the transaction information may be sent directly to server computer 152 of payment processing network 150 from merchant access device 132. For another example, the transaction information may be sent to server computer 142 of acquirer 140 from merchant access device 132, and then server computer 142 of acquirer 140 may subsequently send the transaction information to server computer 152 of payment processing network 150. For yet another example, after identifying merchant access device 132, server computer 152 of payment processing network 150 may directly communicate with merchant access device 132 in order to get the transaction information needed to generate the authorization request message.

In step S560, server computer 152 of payment processing network 150 receives consumer account information and identifies a consumer account using such information.

In some embodiments, server computer 152 of payment processing network 150 may deduce an account associated with consumer using a received phone number. For example, prior to the transaction, phone numbers may be stored in consumer database 158. The phone numbers may be mapped to consumer account identifiers, where each consumer account identifier identifies an account for consumer 110 issued by issuer 160. The consumer account identifiers and the mapping between identifiers and phone numbers are also stored in consumer database 158. In response to receiving a phone number from mobile communication device 120, server computer 152 of payment processing network 150 compares the received phone number with the phone numbers stored in consumer database 158 to determine a matching phone number. Server computer 152 of payment processing network 150 then locates the consumer account identifier associated with the matching phone number. The consumer account identifier may then be used to identify the account for consumer 110 issued by issuer 160.

In other embodiments, server computer 152 of payment processing network 150 may deduce an account associated with consumer using other received account-related information. For example, prior to the transaction, user names may be stored in consumer database 158. The user names may be mapped to consumer account identifiers. Consumer 110 may communicate a user name to server computer 152 of payment processing network 150, for example, via mobile communication device 120. Server computer 152 of payment processing network 150 may then perform matching similar to that described above with respect to phone numbers so as to identify the account for consumer 110 issued by issuer 160. Other account-related information, as previously described, may similarly be used.

In some embodiments, mobile communication device 120 may directly communicate an account identifier to server computer 152 of payment processing network 150. For example, consumer 110 may enter, into mobile communication device 120, an account number or other information recognized by issuer 160 to identify the account issued to consumer 110. The account number may be entered by at least one of an alphanumeric sequence, dialing tone or sequence of dialing tones, image or sequence of images, audio sequence, etc. Consumer 110 may then cause mobile communication device 120 to send such information to server computer 152 of payment processing network 150. In such a case, server computer 152 may not perform matching as previously described.

In step S570, server computer 152 of payment processing network 150 generates and sends an authorization request message to server computer 162 of issuer 160 to facilitate completion of the transaction.

In some embodiments, server computer 152 of payment processing network 150 uses the merchant access device identifier, transaction information, and consumer account identifier to generate the authorization request message. Server computer 152 may extract, from the transaction information, a transaction amount to be authorized. Server computer 152 may then generate an authorization request message which requests authorization of the transaction amount from the consumer account identified by the consumer account identifier. The authorization request message may include merchant access device identifier so that issuer 160 may direct a response to the merchant access device identified by the merchant access device identifier.

In other embodiments, server computer 152 of payment processing network 150 uses the merchant identifier, transaction information, and consumer account identifier to generate the authorization request message so that issuer 160 may direct a response to the merchant identified by the merchant identifier. In yet other embodiments, server computer 152 of payment processing network 150 uses both a merchant identifier and a merchant access device identifier so that issuer 160 may direct a response to at least one of the merchant and merchant access device. In yet other embodiments, server computer 152 of payment processing network 150 does not include a merchant access device identifier or a merchant identifier. For example, issuer 160 may provide the response to server computer 152 of payment processing network rather than the merchant or merchant access device. Server computer 152 may then forward the response to the merchant or merchant access device.

In step S580, server computer 162 of issuer 160 communicates an authorization response message to merchant access device 132. Issuer 160 may first receive the authorization request message, process the authorization request to generate an authorization response message, and then send the authorization response message. Processing the authorization request includes determining whether to authorize or decline the transaction. The authorization response message is a message indicating whether the transaction is approved or declined. Issuer 160 may decline the transaction for a variety of reasons (e.g., insufficient funds, risky transaction, etc.).

In some embodiments, server computer 162 of issuer 160 identifies the merchant access device using a received merchant access device identifier. Server computer 162 may then send an authorization response message to the identified merchant access device. In other embodiments server computer 162 of issuer 160 identifies the merchant using a merchant identifier. Server computer 162 may then send an authorization response message to the identified merchant. In other embodiments server computer 162 of issuer 160 sends an authorization response message to server computer 152 of payment processing network 150. In yet other embodiments server computer 162 of issuer 160 identifies the mobile communication device used in the transaction using, for example, a received consumer account identifier. Server computer 162 may then send an authorization response message to consumer 110 or mobile communication device 120.

FIG. 6 is a flowchart illustrating a method for mobile communication device 120 to facilitate a payment transaction where camera 314 in mobile communication device 120 is used as a vehicle to identify a merchant access device.

In step S610, mobile communication device 120 acquires an image of merchant access device 132. Consumer 110 may have mobile communication device 120 in their possession during the transaction. Consumer 110 may use camera 314 on mobile communication device 120 to acquire an image of portions of or the entire merchant access device 132.

According to some embodiments, the image includes unique characteristics of merchant access device 132 as previously described. The unique characteristics may be sufficient to identify merchant access device 132 from a plurality of merchant access devices. According to other embodiments, the image includes information sufficient to identify merchant 130 from a plurality of merchants. For example, the image may include unique characteristics of merchant 130 as previously described. According to yet other embodiments, the image includes transaction information as previously described. For example, the image may include some or all of transaction information displayed by a display on merchant access device 132.

In some embodiments, consumer 110 may use camera 314 of mobile communication device 120 to acquire an image of only portions of merchant access device 132. The image may include only portions of merchant access device 132 which include characteristics sufficient to identify at least one of merchant 130 and merchant access device 132. The portions may be portions of merchant access device 132 excluding a display of merchant access device 132.

In step S620, mobile communication device 120 obtains location data of mobile communication device 120.
